1. Summary

The City of Unalaska has requested that Electric Power Systems, Inc. (EPSI) provide feasibility design services for the installation of an exhaust gas waste heat to electric energy reclamation project. This report explores the feasibility for the various economic and technical solutions available for implementation.

Upon investigation, EPSI found that the exhaust gas waste heat reclamation system will require an additional waste heat line between the old and new power plants, three exhaust stack boiler units (one on each exhaust stack), necessary higher temperature ORC units, associated seawater cooling and heat exchanging system, supplemental radiator system, associated valving and instrumentation package, one 480V 3 phase feeder stepped up to 4160V and connect into existing Unit 8 and 9 (after Unit 8/9 removal) power lines, and a remote monitoring SCADA interface.

The exhaust gas waste heat project is economically feasible once Unalaska town loads reach minimum continuous year round base loads of 7.5 to 8 MW. Economic feasibility may also become a reality if fuel prices sustain an average price of over $4/gallon. As any one of these factors increase over time the economic feasibility will become more compelling. This conclusion is based on the current available boiler and ORC manufacture data being accurate, conformance to all current and future environmental constraints, and all technical/design issues being appropriately addressed.

The environmental constraints that this report’s conclusions are bounded by concern both air and seawater. It is understood that the current ADEC air permit temperature constraints have been relaxed to allow for the use of exhaust gas stack boiler units such that final stack outlet temperatures to atmosphere do not drop below 350F. However, it should be noted that current ADEC/EPA permitting increases to seawater outlet temperatures have not been permitted to be raised to adequate levels. To support the needs of an exhaust gas waste heat project theADEC/EPA would need to review and permit elevated seawater outlet temperatures before the project could be considered viable. If such permitting cannot be achieved then a costly supplemental radiator system will need to be implemented. For the purposes of this report the cost of supplemental radiators was included.

Performance data, prices, drawings, parts, service, warranty, and lead time information was collected from ORC and exhaust gas boiler unit manufacturers. Below are the manufacturers that have been contacted, equipment reviewed, and evaluated for this report. Below each manufacturer listed is a brief synopsis of their equipment. A more detailed discussion follows further within this report. This report does not focus on ranking and comparing various ORC manufacturers for selection purposes but only gives a cursory review of likely vs unlikely candidates for further investigation. This report will tend to focus on the exhaust gas boiler manufacturer’s pros/cons of each and base pricing upon a select manufacturer solely for the purpose of cost to benefit evaluation.

o Electratherm (ET) Green Machine

This ORC manufacturer produces 50 to 65 kW units. These units were tested at the University of Alaska Fairbanks Mechanical Engineering


10/22/2012 P a g e | 1-5

Department and yielded 5.5%, 7%, and 7.5% total net efficiencies at operating temperatures of 155F, 195F, and 215F, at various flow rates, respectively. Given the flows, temperature differentials, and total available BTUs for the jacket water system at Unalaska it is expected that each Wartsila or Cat will operate two 50 kW machines (plumbed in parallel) at a net output of 39 kW each. This expected net output has been confirmed both by UAF testing and Electratherm trials and calculations. Temperature differentials are not sufficiently high enough to justify the installation of the more expensive 65 kW machines.

o United Technologies Corp (Carrier) (UTC/Pratt Whitney)

This ORC manufacturer primarily focuses on 1 MW unit sizes and larger. However, they do make a 250 kW unit that has only become readily available in the last 5 years. Its optimal operating temperatures are also found to be higher than the 195F that Unalaska can deliver. However, the unit can operate to a limited degree at these lower temperatures. Furthermore, Pratt/Whitney is only willing to sell the 250 kW unit size in lots of ten which is well outside of the scope and budget of this project.

o Infinity Turbine LLC

This ORC manufacturer offers promise in the 200 to 300 kW unit sizes but also has difficulty working with the temperatures. Additionally, they require a money down payment before they will divulge any necessary design information to determine feasibility. AEA grant funding restrictions generally do not allow such payments without proper feasibility reviews.

o Ormat

This exhaust gas and ORC manufacturer produces units that operate at 1000F+ temperatures and utilizes unit sizes much larger in scale than Unalaska would necessitate.

o Ener-G-Rotors

This ORC manufacturer is currently beta testing their 35 to 60 kW units that use a special ORC refrigerant that produces highest efficiencies at lower temperatures around 185F. They do not expect a fully functional unit for sale until the end of 2013.

o GE

GE currently makes a higher temperature ORC unit that grosses 125 kW output. The technology utilizes a hermetically sealed 125 kW high-speed generator and turbine in a single package. It has no external rotating seals and no gearbox. It also uses magnetic bearing technology that creates nearly zero friction losses and minimizes maintenance. It utilizes power electronics to convert high frequency to DC power which is then reconditioned to 60 Hz usable power output. This unit may have application for the exhaust gas waste heat reclamation project. The minimum operating evaporator temperatures require 300+F which can be achieved from the exhaust gas boilers reviewed in this report.


10/22/2012 P a g e | 1-6

o TAS

This ORC manufacturer produces their smallest units at 800 kW which is of a much higher scale and output than Dutch Harbor can support.

o Turbo Thermal LLC

This ORC manufacturer produces units in the 80 kW size and can bundle 3 or 4 units together in a modular package for a total maximum net output (after pump load is subtracted) of 225 to 300 kW. The R123 refrigerant they use in their units yield a theoretically calculated 7.6% and 11% efficiencies based on the total available jacket water heat and exhaust gas heat sources @ 195F and 300F, respectively. This ORC manufacturer appears to have the most comprehensive calculation foundation upon which their efficiency numbers are based. These efficiencies are also in agreement with Electratherm’s actual tested performance values.

o Echogen

This ORC manufacturer produces 200 to 300 kW units that operate in the 450F to 1000F operating temperatures. This will not work for this project as 300F temperatures are the maximum available temperatures that can be delivered at Dutch Harbor.

o Calinetix

This ORC manufacturer is no longer in business having been recently purchased by GE. Some of the Calinetix technology may have been adopted by GE.

o Cain Industries, Inc.

This exhaust gas boiler unit manufacturer produces a unit than can provide hot water temperatures in the 215F to 230F range where most ORC manufacturers prefer to operate. The Cain is least expensive and largest of the exhaust gas boiler units evaluated. It has several advantages that make it the most affordable of all units throughout its life. Cain provides a complete self-monitoring and self-cleaning low maintenance product that would suit the needs of the project. The controls package monitors in/out exhaust gas temperatures to avoid condensation of sulfuric acid. It also monitors exhaust gas back pressure (to avoid compromising engine efficiency) and provides regular self-cleaning cycles utilizing either steam or compressed air. Maintenance access points are readily available, includes integral exhaust bypass valve and valve controls, and there is good relatively local support of this product. Approximate material cost (not including installation labor) per boiler with all controls included is $235,000.

o Maxim

This exhaust gas boiler unit manufacturer produces a unit that can provide hot water temperatures in the 215F to 230F range where most ORC manufacturers prefer to operate. They do not offer the same built-inready-to-go self-monitoring package that Cain does and would thus require additional cost to integrate a controls package to be comparable


10/22/2012 P a g e | 2-7

to the Cain unit. Furthermore, maintenance service for this unit is very difficult as maintenance access is only available with major disassembly, cleaning, and reassembly of the unit. This would also require crane time and coordination. Support, however, is available relatively locally.

o Aalborg

This exhaust gas boiler unit manufacturer produces a unit that can provide hot water temperatures that would be needed for this project. Aalborg makes a low weight, compact, easy to maintain, highly efficient,proven design, tailor-made for specific requirements, designed for diesel applications, vibration resistant units. They can provide many references for similar installations. However, Aalborg does not offer an integral exhaust bypass valve and check valve for use with existing exhaust systems. Also, a third party controls/monitoring instrumentation package would need to be developed and integrated into this boiler unit adding further cost and complexity. Approximate material cost only per boiler plus third party controls is $320,000.

2. Facility Evaluation ��

EPSI looked at each of the existing generator units at each powerhouse to determine if the individual heat inputs to the “system” would be viable sources to size the ORC units to be as large as possible. There are two heat sources from which the waste heat project is being developed 1) Engine jacket 2) Exhaust Gas. Both heat sources will require the use of ORC units. While there is much more heat energy to reclaim through the exhaust gas than engine jacket the exhaust gas system will require additional equipment over the engine jacket system.Currently, Units 10, 11, and 13 (new plant) are connected through common engine jacket water waste heat lines and are available for electric conversion according to the BTU amounts shown below in this section of the report.

In the old powerhouse building, Units 1 through 6 have been decommissioned and removed. Units 8 and 9 in the old powerhouse and Units 10, 11, and 13 in the new powerhouse are currently in service. All are of a size to provide sources for the ORC units to a certain degree especially with the addition of an exhaust heat recovery system. However, units 8 and 9 are not connected to the existing engine jacket waste heat lines and are expected to be decommissioned and removed in the near future. Therefore, units 8 and 9 are not evaluated for waste heat reclamation potential within this report. Currently, units 10 or 11 are typically base load units, with Units 8 or 9 supporting the remaining loads. Therefore only Units 10 and 11 areconsidered for exhaust gas waste heat evaluation within this report. In the future, it may be further beneficial to expand the exhaust waste heat system to include additional units as they are run on a more regular basis. Town loads need to be consistently around 7 MW minimum before unit 13 with unit 10 or 11 OR both Wartsila’s would need to be regularly dispatched. Current loading still remains between 5 MW to 7.5 MW where 7.5 MW is rarely approached.


10/22/2012 P a g e | 2-8

The actual building heating loads for the concrete and steel powerhouses currently extract up to 500,000 BTU/hr from the engine jacket water waste heat system. EPSI recommends continuing to serve the building heating loads from the existing jacket water waste heat system.

EPSI, through facility personnel and manufacturers data, was able to determine normal operating conditions for the following units. All evaluation calculations will be based upon 75% unit loading. Units 8 and 9 are not included in this evaluation but are factored into the unit dispatch schedule to support the town loads such that Units 10, 11, 13 only turn on when 75% loading on these units can be expected.

Unit 10 – Wartsilla 12V32

Hours per year operation: 4,380

Typical operating load: 75% - 4 MW

Heat Rejected to Jacket Water @ 75% loading: 3,586,000 BTU/hr

Jacket Water peak temperature and flow at ORC: 195F @ 440 GPM

Heat Rejected to Exhaust Gas @ 75% loading: 5,775,000 BTU/hr

Exhaust Gas peak temperature and flow at ORC: 300F @ 221 GPM

Unit 11 – Wartsilla 12V32


Typical operating load: 75% - 4 MW

Heat Rejected to Jacket Water @ 75% loading: 3,586,000 BTU/hr




Unit 13 – Cat C280


Typical operating load: 75% - 3.3 MW

Heat Rejected to Jacket Water @ 75% loading: 2,798,000 BTU/hrJacket




Total plant operating heat capacity (all units jacket water + all units exhaust gas @ 75% loading): 27,309,000 BTU/hr

Total plant heat capacity (Total plant operating heat capacity minus building heat load) for ORC: 26,809,000 BTU/hr.

Actual current available heat (based on today’s town system electrical loads = one Wartsila jacket water plus one Wartsila exhaust gas minus building heat loads) for ORC: 8,861,000 BTU/hr.


10/22/2012 P a g e | 2-9

Actual current available heat only from Wartsila or Cat exhaust gas energy conversion at the gas boiler 5,775,000 or 5,789,000 BTU/hr, respectively (building heat to be supported on jacket water system).

Exhaust gas boiler is conservatively estimated at 90% efficient. This means that 5,197,500 BTU/hr of waste heat energy can be expected to be delivered to the ORC units from each Wartsila and 5,210,100 BTU/hr from the Cat.

Current energy production reports reveal that Unalaska is produces 15.5 to 16 kWh per gallon of fuel consumed. This report will use 16 kWh/gal for evaluation purposes.

From correspondence with Electratherm and Turbo Thermal LLC technical representatives for Units 10, 11, and 13 it appears that at most the following waste heat energy could be reclaimed from each of the indicated units:

Wartsila or Cat C280 jacket water only: Expected ORC output 78 kW after building heat is served (39 kW on each of two separate Green Machines)

Wartsila or Cat C280 generator exhaust via exhaust stack boiler: 167 kW per unit (11% ORC efficiency and 90% boiler efficiency).

Recommended plant operating Temperatures: Exhaust boiler supply temperature (hot): 300 degrees F Exhuast boiler return temperature (cold): 250 degrees F or as recommended by

boiler manufacturer Waste heat System operating:

To ORC: 300 degrees F Building Heat: 250 Degrees F

Concrete powerhouse building structural Generator units 1 through 6 have been removed from the first floor back room of the old power plant building, leaving space for installation of the new ORC units on this concrete slab-on-grade floor, making structural analysis unnecessary. Additionally, construction on the first floor will be the least expensive as all hot water, cold water, and electrical connection points are located on the first floor.

Preliminary evaluation has shown that the second floor can bear up to 100 lbs/sq. ft. Detailed structural design will be needed to determine and avoid compromising the rebar. The UTC 250 kW unit weights appear to fall below this weight restriction and can be therefore safely assumed that most any manufacturer of this size unit will also meet the weight restrictions.

For the purposes of this report costs will be focused only on the first floor construction.

Electrical Integration of either ORC Unit(s)

The electrical modifications required for the installation of the ORC units are rather limited in scope as they do not require many modifications to the existing facilities.

The ET Green Machine may be custom ordered to generate at various voltage ratings. The intent will be to order the ORC in the standard 480V 3-phase configuration and connect it to the existing 480V building service in the concrete power plant. This will allow the ORCs to serve all


10/22/2012 P a g e | 3-10

480V loads in the steel and concrete power plant buildings as well as export any surplus to the 4160V new plant generation bus for delivery to the distribution system.

The maximum allowable power that can be exported to the steel building is 332 kW via the available 400A 3 phase 480V plant-to-plant station service feeder between each MDP. Refer to electrical one-line in Appendix A. Should the need arise for more than this amount then the existing 4160V concrete plant system would need to be upgraded or Units 8 or 9 be removed to accommodate. Calculations show that when all units sustain 75% loading (utilizing exhaust gas and jacket water less building heat) approximately 600 to 650 kW of ORC power could become available. This level of loading would require sustained electrical town loads of 11 MW which is over 100% of current day town loading.

3. ORC Evaluation

Given the many technical design constraints EPSI has determined that both waste heat systems (engine jacket and exhaust gas) are ideally suited (both electrically and physically) for ORC units in the 40 kW to 80 kW range and would be capable of operating around 190F to 300Fcontinuously. This restricts the selection process to only a very few ORC manufacturers today which include Ener-G-Rotors, Electratherm, Turbo Thermal LLC, and GE. Many other manufacturers were considered but were eliminated from the “potential candidates” list for this project because of lack of interest, operating temperature problems, or unit size scaling issues. Ener-G-Rotors is still currently in beta testing mode and does not expect to produce a commercially available 35 kW to 50 kW unit until December 2013. Electratherm produces the commercially available Green Machine Series 4000 unit that is a 50 kW unit which is ideally suited for use on the jacket water system and/or exhaust gas heat system. Turbo Thermal LLC produces a 240 kW or 320 kW ORC unit that can be broken down into three or four 80 kW units which appear to be more ideally suited for the exhaust gas system. GE Clean Cycle units are 125 kW units that may also work in leau of the Turbo Thermal units on the exhaust gas system.

The engine jacket water waste heat to energy project was evaluated in the EPSI 2008 report. During the 2011 Request for Qualifications process only Pratt/Whitney UTC responded. Unfortunately, Pratt/Whitney UTC will now only sell a minimum lot of ten units per order which eliminates them from the “potential candidates” list for this project.

Below is a brief description of the Electratherm and Turbo Thermal ORC units and the rationale for their further consideration. The summary of this report lists each of the other manufacturers not mentioned within this section. The reasons for their elimination from the “potential candidates” list are briefly outlined in the summary of this report.

�� !��

The Electratherm (ET) units are more customizable than any other ORC vendor information to date. ET, through their website and communication with the ET representative, has two standard models which fit a variety of applications and unit (heat source) sizes. The electrical output range is also ideally suited to run two 50 kW units for each engine jacket.

The ET Green Machine 4000 is a 50 kW unit that consists of a 480V 3 phase 100 HP screw compressor operating in reverse process. The generator consists of a Marathon 50 kW


10/22/2012 P a g e | 3-11

induction motor run in reverse operation. The induction motor makes for an inherently safe concept such that no export of power is possible should there be loss of AC power on the prime power source side. Additionally, this eliminates the need of synchronization equipment. The entire assembly (including control panel) sits on one skid and has a physical footprint size of approximately 6’ x 8’ x 8’.

The first floor space, where recently retired units 1 through 6 resided, is physically restricted to only accommodate units of this size or smaller. Up to three separate units can fit within this existing space. Room for a fourth unit may be provided if the old operator’s office becomes available for renovation to accommodate.

Electratherm is willing to customize any of its units to meet the needs of the facility. For this reason information concerning the “base” units has been provided. Customization of the units to optimize the recovery would cause the price to adjust accordingly. Titanium or cupro-nickle in shell and tube configuration heat exchangers are options for use with the sea water cooling system at additional cost.

!��"��#��$�The ET ORC has three moving parts which require maintenance. In general, ET recommends that the turbine drive belt, should be changed annually even though it is rated for over 20,000 hours of operation. The cost of the drive belt is $300. ET has determined that each unit would require 1.5 cents per kW-hr for maintenance over a one year period. This cost would include periodic inspection of the unit (lubrication, seals, performance) and cleaning of the units’ sea water heat exchanger and replacement of the drive belt.

ET is a new company/manufacturer and unfortunately does not have years of previous ORC experience to be able to adequately predict the longevity of their units. But, from a design perspective, their unit has 3 moving parts. Based on this fact alone, we would anticipate that the unit should have well over a 20 year life expectancy.

�� %��&��%��''��

This ORC manufacturer makes two different sizes of units that could work well for this project. The first size is a 240 kW unit which consists of 3 (three) 480V 3 phase 80 kW rated expander/generators working in unison. The second size is a 320 kW unit which consists of 4 (four) 480V 3 phase 80 kW rate expander/generators working in unison. The optimal operating temperatures are at 300F but can also run at the expected 230F temperatures at the expense of efficiency as mentioned below.

Both units (240 kW and 320 kW) each fit within a 20 foot shipping container and can be broken down and refitted to most any space. The largest pieces of gear consist of three major components: 1) Three or Four expander/Generator skids each @ 30”W x 30”H x 72”L; 2) One common surge tank @ 72”H x 48” diameter; 3) One common control panel @ 72”H x 48”W x 30”D (double door).

Approximately every 25F above 230F up to 300F an extra percentage point of efficiency is achieved. For example, at 225F output to the Turbo Thermal ORCs one can expect 8% efficiency. At 250F one can expect 9% efficiency, 10% efficient @ 275F, and 11% efficient @ 300F. For this analysis it is assumed that the exhaust gas boilers can be turned up to 300F output to the ORC units to achieve 11% efficiency from the Turbo Thermal ORC units.


10/22/2012 P a g e | 4-12

All generators are Westinghouse Premium efficiency (SF = 1.15) 480V 3 phase 100 HP induction motors. This makes for simplification of controls and a safe electrical system.

!��"��#��$�Turbo Thermal has determined that each unit would require 1.0 cents per kW-hr for maintenance over a one year period. This cost would include periodic inspection of the unit (lubrications, seals, performance) and cleaning of the units’ sea water heat exchanger and replacement of the drive belt.

�� (��

These higher temperature ORC units are compact, relatively light weight, and can be broken down and rebuilt to allow for installation in smaller spaces. However, the evaporator and condenser components would have to be provided by the customer at additional cost. The estimated efficiencies are between 9.5% and 10.5% at 300F/55F hot/cold for the given flows and waste heat energy available from each of the Wartsila and Cat exhaust gas stacks.

It’s estimated that each Wartsila @ 75% loading can energize 1.1 (137.5 kW) ORCs. It’s also estimated that the Cat @ 75% loading can energize 1.4 (175 kW) ORCs.

4. Exhaust Gas Boiler Evaluation and Integration at Powerhouse

Below are the design and construction constraints that should be considered when implementing the exhaust gas waste heat reclamation project.

1. The existing waste heat system, as designed, is connected and in common to the engine jacket water systems for Units 10, 11, and 13, and currently provides up to 195F water temperature. This temperature is too low for many ORC units to operate effectively,some manufacturers’ such as Electrotherm and potentially Ener-G-Rotors, can operate at reasonable efficiencies that can still economically justify the project. Modifications to the system flow rates will need to be implemented such that the waste heat peak temperature could be raised to 195F where these ORCs can be operate at better efficiencies. This modification could be implemented at any time at little to no cost.

2. During construction of the steel powerhouse new 8-inch waste heat transfer piping was installed between the steel powerhouse and the concrete powerhouse to allow for transfer of waste heat to the seawater heat exchanger and the then-future ORC units. However, higher temperature waste heat from the exhaust stack boiler may require the installation of new heat transfer piping from the exhaust gas boilers to the ORCs, which are to be installed on the first and/or second floor of the concrete powerhouse building.

3. Since the exhaust gas boiler lines could operate at much hotter temperatures (around 230 - 300F) than the engine jackets could handle it further suggests that a separate exhaust gas waste heat line be installed.

4. It was considered that the existing jacket water waste heat lines be cut, intercepted, and rerouted to the new gas boilers to save cost. However, after reviewing available BTU outputs from each heat source it was clear that removing the engine jacket waste heat lines would severely limit the availability of waste heat extraction as a whole. Therefore, since a substantial amount of the entire waste heat project centers around the engine jacket system it is critical to leave it intact and develop new higher temperature waste heat lines for the exhaust gas system.


10/22/2012 P a g e | 5-13

5. As part of the detailed design for the ORC’s a revision to the facility sea water cooling permit may be required to allow for a more elevated discharge seawater temperature than originally permitted. Preliminary data from the ORC vendors indicates a sea water temperature increase of 20F. No sea water temperature restriction was provided to the ORC vendors. Something to consider is that as waste heat is converted to electricity the amount of waste heat/cooling water which requires cooling will be reduced. When the ORC’s are operating at their peak output, the sea water discharge temperature could decrease. If the sea water permit cannot be successfully modified then a supplemental radiator will be needed to remove excess heat prior to dumping remaining heat back into the seawater.

6. According to Wartsila 12V32 design information (from original 2005-2007 design effort) the units are designed to allow a total exhaust restriction of 12 inches of water column. It’s currently estimated that the total system back pressure with the exhaust gas boiler will be 11.35 inches of water column. This is a worst case operating point without detailed design. As such the gas boiler control package should include differential pressure monitoring and alarming.

7. One or two motor operated valves to control sea water flow to the heat exchangers and the bypass around the heat exchangers will be required. This is only a preliminary look at the system, during the detailed design; this strategy would have to be verified.

8. The ORCs operate best at steady state conditions and are not suited for operation on a peak-shaving or back-up unit. This would best be provided by the Wärtsilä units as the base loaded machines. Currently, only one Wartsila or the other is used on a nearly 24/7/365 basis. Eventually, as the town loads increase the Cat C280 will be utilized in a similar fashion at which point another exhaust gas stack boiler could be implemented.

9. It’s suggested that a 50/50 Dowfrost HD/Water solution be used to transport the 300F exhaust gas boiler outlet temperatures expected. This will provide the optimal heat transfer, eliminate chemical breakdown, satisfy environmental requirements, and contain the needed corrosion inhibitors.

5. Conclusion and Recommendations

EPSI recommends that the engine jacket water waste heat project be fully constructed to completion so as to reap the most immediate and rewarding benefits possible. This should be accomplished through the installation of 4 (four) 50 kW Electratherm Green Machines installed on the lower floor of the concrete plant where units 1, 2, 3, 4, 5, and 6 used to reside. Since plant operating procedure is based on maintaining N-1 unit contingency (plant always allows for one of the largest units to be offline at all times) it is not necessary to evaluate for loading above N-1 plant capacity.

As funds become available the project could be expanded to include the use of an exhaust gas waste heat system. EPSI recommends that this be accomplished via the use of two 240 kW Turbo Thermal LLC ORC units (or any equivalently sized units capable of effectively handling 230F to 300F heat transfer fluid) installed on the second floor of the concrete plant building after demolition of units 8 and 9 is accomplished. This will open up the needed floor space for any supplemental radiator system, 480:4160V step-up transformer and 4160V cabling needed while maximizing the use of the available exhaust gas waste heat available for electric conversion.

EPSI recommends that one Cain Industries gas boiler unit be installed on each of the three steel plant exhaust stacks (Units 10, 11, and 13). Cain Industries boilers are chosen because


10/22/2012 P a g e | 5-14

they provide the most complete package including all necessary controls and monitoring that other manufacturer’s do not offer. Furthermore, by comparison the Cain units are much easier to maintain, ensuring long project life. Below are the costs, fuel displacements, and estimated payback periods for both waste heat systems now and into the future.

exhaust heat recovery

SYSTEM FUNCTIONBtu is transferred from the exhaust stream to heat sinks suchas water, glycol, therminol fluids, or steam production. Suitable fuel types for combustion sources include natural gas,propane, digester gas, diesel fuel, and light to heavy fuel oils.

PROPOSAL CONSIDERATIONS• Large or irregular exhaust connections• High or varying exhaust temperatures• Particular pinch point requirements• Exhaust or liquid control• Special heat sink requirements• Special heat transfer metallurgy requirements• Specific maintenance concerns• Optional equipment requirements• Installation space and weight concerns• Package system requirements

ANTICIPATED RESULTS• Tremendous fuel savings typically pay for equipment

and installation within 1 to 3 years of average use.• Pollution reduction due to lowered annual fuel usage.• Lower exhaust temperatures and significantly reduced

sound output levels (final sound attenuation is typically 15 - 25 dBA).

INTRODUCTIONThis catalog covers the Cain Industries Product lines for the gas anddiesel engines, gas turbines, and micro turbine generator retrofitapplications. For these applications, we offer over 500 standardproducts to choose from, and can typically provide a comprehensiveanalysis and quotation to fit your exact needs within 24 hours. Ourequipment can be adapted and assembled to fit any application orcomplete installation.

COGEN APPLICATIONS• Hospitals• Manufacturing Plants • Schools• Office Buildings• Shopping Malls• Drilling Platforms• Oil & Gas Plants• Marine

EQUIPMENT VARIETY• Exhaust steam generators• Large exhaust recovery silencers• Smaller specialized exhaust recovery silencers• Special heat transfer configurations• Recirculating engine jacket water boilers

EXHAUST STEAM GENERATORThe fully packaged ESG1 is selected from 48 pre-engineered standard models with output capabilities of 20 to 500 boiler hp and operating steam pressures from 3 to 450 psig. The ESG1 is shipped complete, readyfor operating as either a primary or supplementary steam source.

The ESG1 package is made up of threebasic sections: • finned tube heat transfer section• steam flash circulating drum assembly • modulating full port exhaust bypass system

OPERATION & CONTROLThe integral forced circulating water pump continually circulates high temperature water from the steam flash drum assembly to the heat transfercore assembly. Btu is transferred from the exhaust to a high flow superheated water/steam mixture. The super-heated water is returned to the steam drum which contains dry pipe, baffles, and lance assemblies, where it flashes into 99% dry stream as its exits out to the system.

As the water is generated into steam and exits the boiler, the modulating boiler feedwater system controls continuous feedwater flow for constant drum water level control. Fail safe controls are built in for full exhaust bypassin the event of electrical or pneumatic loss.

The steam pressure controller maintains the operating steam pressure as it con-trols the modulating exhaust bypass assembly. This provides solid operating steam pressure under various operating steam load demands.

QUALITY CONTROLThe ESG1 is manufactured, tested, and stamped in accordance with the requirements of Section I of the ASMEBoiler and Pressure Vessel Code, and National Board. Boilertrim includes all safety controls and alarms to meet state andfederal codes. Final assembly, electrical wiring, and factoryadjustments are completed under a strict set of guide lines.

FEATURESThe ESG1 is an easy choice when compared to the“old technology” of a conventional firetube boiler:• Completely self-contained “package” design reduces

engineering, installation and maintenance costs.• Size requires only 1/2 the floor space and 1/2 the

weight of conventional boilers, which reduces build-ing size, structural support costs, and shipping costs.

• Ease of tube replacement requires no overhead cranes, special rigging, special crews, or extra roof height above the unit, while reducing down time.

• Many shapes and sizes are available to fit limitedspace and maintain performance requirements.

• Produces greater than 99% dry steam.• Provides 100% turndown capability.• 5–10 minute time from startup to full output.• Integrated exhaust modulating bypass for safe auto-

matic steam control.• Explosion-proof heat transfer exchanger.• Low friction loss for minimum static exhaust back

pressure.• High circulating flow to minimize scale buildup.• No thermal expansion concerns with cold boiler

feedwater.• Performance aimed at the lowest pinch point in the

industry, (final leaving exhaust temperature minus operating steam temperature) for maximum thermal efficiency.

MINIMUM CONNECTIONSThe ESG1 requires only the following connections for a cost effective installation:• steam outlet• exhaust flange inlet and outlet• single main power • single main blowdown• feedwater inlet• pneumatic control air• cooling water inlet and outlet

TIMED AUTOMATICSOOTBLOWER (optional)The exclusive Cain Industries Timed Automatic Sootblower design is applied to combustion sources where the sulphur content is highand/or combustion efficiency is poor. When a soot layer accumu-lates on the heating surface to a thickness of 1/8”, fuel consumptionis increased by 8.5%. The sootblower is also applied when it is not cost-effective to open inspection doors and clean the exchangerby other means. The sootblower system will continually keep theheating surface at a high performance level and eliminate the day-to-day operator expense and engine down time.

The blowdown sequence occurs while the engine is in full operationand is fully adjustable. The special flood-jet type nozzles achievemaximum cleaning velocity using steam or air as discharged throughan electric control valve (included). Together they form a `continu-ous knife edge concentrated spray pattern’ surrounding the heatingsurface. This `ring nozzle assembly’ as attached to a manifoldedflexible steel hose assembly, is powered up and down by a pneu-matic drive cylinder. Dual timing relays allow complete control for30 second cycle duration and intervals specific to each application.Final results are controlled double cleaning action, insuring that themaximum Btu recovery and anticipated savings are achieved.

LIQUID TEMPERATURECONTROL (optional)Operating Sequence: During a cold startup the exhaust bypass willbe powered to the normal operating position. As the liquid temper-ature rises and approaches a preset point, the exhaust bypassdamper will begin to move to the temperature control position.When the desired temperature is completely satisfied the damperactuator will move to the maximum open position, bypassing 99% ofthe exhaust flow (100% bypass cannot be attained due to someleakage and residual heat in contact with the fin tubing). Included isa 4-20 mA output controller, thermocouple, thermocouple weld andwire, and modulating bypass actuator installed, wired, and tested,for a single 120 volt, 1ph, 60hz power connection.

• Capacity: 200kW – 10MW• Entering gas temps: to 1,600°F• Heat sink types: Process water,

boiler feedwater, ethylene glycol, or thermal transfer fluids

U-TUBE RECOVERY 1The UTR1 is applied primarily where confined area restrictions vs heat transfer requirementsmust be considered as a priority, secondarily to the features the HRSR. Its compact industri-al design allows for maximum Btu recovery relative to the space allotted for installation. Finned tube spacings range from bare tube heating surface up through 8 finsper inch, depending on the fouling factor requirements. Standard fin to tube attachmentusing the nickel braze/weld fin-to-tube process allows no fin-to-tube separation to 2,000°F.

The UTR1 can be located above the engine or on the floor for convenient installation. Withover 170 standard configurations to choose from, the UTR1 can be designed to meet theclosest pinch point requirements when installation space is not an issue. Easy access allowsfor quick removal of finned tube rows or core assemblies without disturbing the exhaust gasconnections, and allows for routine inspections and/or cleaning requirements.

Message:

As requested, please find your proposal attached for a different model for the new conditions. The Stack Corrosion Control Assembly (SCCA) has been added because of the customer’s exhaust gas temperature concerns. Please see the “System Descriptions” section of the proposal. Cain recommends that they use the exhaust gas bypass to control the exhaust gas temperature of the HRSR, and not attempt to control it by varying liquid flow rtes. We recommend this method in order to reduce the possibility of localized boiling, over heating of the liquid, and deposits on the inside of tubes that can be the result of too small of a liquid flow rate. The quoted price is for (1) unit, F.O.B. Cain Industries. Shipment is typically in approximately 10-12 weeks after submittal approval for 1 unit. The terms of sale, Bulletin #25500 form part of this proposal. See this bulletin for payment terms.

Cain Industries is pleased to propose the following HRSR model exhaust heat recovery unit to recover exhaust heat from a diesel fired, Wartsila 12 32 engine. The recovered heat will be transferred to a 60/40 ethylene glycol/water loop .

The HRSR heat recovery unit features: a full port exhaust gas bypass individually removable, type 316 stainless steel tubes with 304 stainless steel fins a stainless steel interior shell 3 of factory insulation (less liquid header assemblies) a 10 gauge carbon steel exterior shell and a hinged full face access door(s) for inspecting and/or cleaning the finned tubes.

The finned tubes are compression fitted to the liquid headers. Tube replacement does not require welding.

The exhaust gas bypass is stainless steel with stainless steel flanges.

The heat exchanger section has 3 thickness factory insulation. The exhaust gas bypass will have 3 thickness blanket wrap insulation. The liquid headers are not insulated and field insulating is recommmended.

The iquid Temperature Control Assembly ( TCA) automatically modulates the exhaust gas bypass to control the temperature of the heated glycol/water leaving the heat exchanger. A desired maximum temperature is entered on the digital indicating controller. The controller has a continuous temperature display, and ODB S communications which will allow remote monitoring of the process variable and control of the set point. Thecontroller will be dual input and will switch to exhaust gas temperature control if the exhaust

System Description:System Description:System Description:System Description:






System Description: (cont)System Description: (cont)System Description: (cont)System Description: (cont)gas temperature falls below a preset minimum temperature (355F). Either process variable, maximum liquid temperature out or minimum exhaust gas temperature out, can be set remotely. Contacts will be provided to remotely drive the exhaust gas bypass to the bypass position. The panel is approved.

The Cain Timed Automatic Sootblower has ring nozzle assemblies that travels the length of the heat exchanger while jetting steam or air at the finned tubes. The travelling action of the sootblower, along with the single row arrangement of the finned tubes, ensure coverage of the finned tubes by the steam/air jets.

not meet performance requirements when determined by standard test procedures, Cain will make correc-

tions it deems necessary at its option under the limitations of this warranty. Any alterations or repair of Cain

from excessive vibration resulting from isolating vibration protection not properly installed where required.

This warranty does not cover damage resulting from expansion due to expansion joints not properly installed

ed deficiency such as soot build up on the heating surface. Cain makes no other warranties of performance

eters from the equipment. Exhaust gas and liquid volumes shall be determined by actual measurement, if

practical, or by calculations if necessary. All factors of O2, CO2, excess air, full input, altitude and the oper-

ating efficiency of the primary direct fired unit, shall be incorporated in the final determination and calculation

Proposal/Quotes: #3232 #3233 #3234 #3235: ElectraTherm Series 4000 Green Machine - Water Condenser Project: City of Unalaska: Dutch Harbor Power Plant Heat: Engine Jacket Water - with closed loop fresh water condensing City of Unalaska Dutch Harbor Power Plant Dear City of Unalaska, Find in the following proposal McKinley Service & Equipment, Inc.’s (MSE) Quote and updated PEF Assessment for the first of 3 Series 4000 Green Machines for installation at Dutch Harbor in the City of Unalaska. In accepting this Quote, please affix your Purchase Order Number to the box and your signature to the space at the bottom left of the second page following this letter. Please email the signed Quote to me for review. Upon acceptance I will return a signed copy to you. This Quote contains a number of special terms and conditions worthy of highlighting here:

� The shipping estimate includes shipping the first of three Series 4000 Green Machines and 700lbs. of refrigerant in a single 20ft. shipping container.

o MSE is currently awaiting approval from Honeywell to ship the refrigerant in the same container as the Green Machine. If they cannot be shipped together there will be an addition shipping cost for the refrigerant.

� Acceptance Period shall follow 90 days of ‘run time’ as determined solely by MSE staff. Full payment shall then be immediately due and payable.

o The offer of this “demonstration” is predicated on the End User Customer’s purchase of the second and third machines per upcoming quote #3234 and #3235 should the Acceptance Period for the first machine be deemed successful.

o Shipment of machine #1 from ElectraTherm’s place of manufacture on or before December 31, 2012.

� We are including Quote #3234 and #3235 for Machines #2 and #3, should the City wish to employ the “demo” terms, with one possible exception:

o The single shipment of 2 machines plus 1400lbs. of R245fa will likely require use of a single 40ft. shipping container, so the price of shipping machines 2 & 3 will likely be less than the per machine shipping costs in this Quote #3232.

� MSE is confirming the price of R245fa and these shipping arrangements with Honeywell, and is awaiting their comeback since EPS confirmed that ElectraTherm/McKinley is to supply refrigerant.

� The cost of the return of the cylinders to Honeywell shall be the responsibility of the City of Unalaska and is not included in this quote.

� City of Unalaska must supply internet access, (see Exhibit D), to comply with the warranty. Cellular or Satellite internet available at an additional cost.

Feel free to contact me directly with questions pertaining to the project and quote by email or by telephone at 907-262-2685. Sincerely,

Matt McKinley - Business Manager McKinley Service & Equipment, Inc. [email protected]

Turning heat into power

Discover a way to get more from your reciprocating engine with the Clean Cycle generator

a product of

Turn your reciprocating engine heat into additional power Heat is a by-product of reciprocating engine operation, but it is often released

into the atmosphere and not fully utilized. GE can change that: the Clean Cycle1

power generator from GE’s Heat Recovery Solutions division captures energy in

the form of heat and converts it into usable energy in the form of electricity.

making a simple concept more versatileThe Organic Rankine Cycle (ORC) has been used for decades in large power

generation applications throughout the world. GE’s Clean Cycle module integrates

innovative technologies enabling small-scale heat to power applications.

Heat is captured from the engine exhaust and water jacket in heat exchangers.

Organic fluid in the ORC is pumped through the heat exchangers, exposing it to the heat source.

The heat converts the fluid into a superheated vapor, whichis expanded across aturbine, causing it to spin.

The turbine is integrated into a power module, which creates electricity that can be sold to the grid or used onsite.

After passing through the Integrated Power Module, the vapor is cooled back to a liquid, and the cycle repeats.

Advanced technology for effi cient and reliable power generation

- The Integrated Power Module is a hermetically sealed 125kW high-speed generator

and turbine in a single package. It has no external rotating seals and no gearbox.

- Magnetic bearing technology within the Integrated Power Module results in a non-contact,

cleaner (no oil required), more effi cient (minimized losses) and low-maintenance solution.

- Sophisticated power electronics automatically match the voltage and frequency

of the electrical grid, enabling the Clean Cycle to connect directly to it.

oil & petroleum

Engines that compress natural gas produce heat, but often

do not have a use for it nearby. Engines using associated

petroleum gas to generate electricity often face a similar

situation.

independent power producers

Natural gas and diesel engines, as well as engine compressors,

all generate heat, and can be found in nearly every corner of

the world.

Many industries can benefit from GE’s Clean Cycle technology

waste treatment

Landfills and wastewater treatment plants present

opportunities to convert captured gas into electricity

via an engine.

lumber, milling & timber

Wood, refuse, and other waste can be converted into

a syngas - a low-emission fuel source for engines.

agriculture, greenhouse & food

Biogas, created by digesting food and agriculture waste, and

biodiesel can be used in engines. Natural gas is also used to

fuel engines in greenhouse applications.

metals, mining & chemicals

Captured methane from mines, steel gas, and special gases

from the chemicals industry are all harmful if released into

the atmosphere. Instead, they can serve as a fuel source for

engines.

GE Energy

increased power output

- The solution generates up to 125kW of electricity (gross).

- No incremental fuel is required. The technology runs entirely

on reciprocating engine heat.

- A complete installation typically is 5 % more efficient than

a reciprocating engine alone, and creates up to 10 % more

power.

reliable and consistent performance

- The technology automatically tracks the engine heat, so

it runs even on engines that have varying output levels.

- Power electronics seamlessly integrate with the electrical

grid, making it simpler to sell the power or offset local

power costs.

- Clean Cycle units require minimal maintenance.

proven results for a range of installations

- The Clean Cycle solution is suitable for new and retrofit

reciprocating engines.

- Installations are scalable: Multiple units can be installed on a

single reciprocating engine, and one unit can be installed on

multiple engines.

- Installations may qualify for additional incentives, depending

on location and fuel used in the reciprocating engine.

The Clean Cycle system has received GE’s ecomagination

qualification for its ability to provide customers with cost-saving

and environmental benefits, such as the generation of about

1 million kWh of electricity and the avoidance of 350 metric tons

of CO2 per year in combination with a reciprocating engine1. That

equates to the annual electricity consumption of 240 European

households and the annual CO2 emissions of almost 200 cars

on European roads. Ecomagination is GE’s corporate-wide

initiative (www.ecomagination.ge.com) to use and develop new

technologies that help customers meet pressing environmental

challenges.
